SpaceX to Launch Twice in December?
(Source: Advanced Television)
SpaceX, still suffering from a September 1st fireball catastrophe that
destroyed an Israeli-owned satellite, is reported to be readying two
rockets for launch in December. One Falcon 9 rocket has been delivered
to Vandenberg Air Force Base in California. Prime candidate for this
particular launch would be the Iridium communications fleet of 10
satellites and much delayed and needed by the operator. The launch has
already been postponed from July and September.
The other rocket is reportedly being tested at SpaceX’s McGregor test
facility in Texas, ahead of being shipped to Cape Canaveral (launch pad
39A). Pad 39A has been refurbished by SpaceX while the nearby Pad 40 is
being repaired following the explosion in September. This launch could
be the – also much delayed – EchoStar 23 satellite. Local reports from
Florida suggest that it could be as late as December 30th before the
Cape Canaveral launch takes place. (11/24)
EchoStar Expects Jan. 8 or 9 SpaceX
Launch, Confronts Brazil and EU Deadlines (Source: Space News)
Satellite fleet operator EchoStar Corp. on Nov. 23 said its EchoStar 23
tri-band telecommunications satellite for Brazil is expected to launch
Jan. 8 or Jan. 9 aboard a SpaceX Falcon 9 rocket from Kennedy Space
Center, Florida.
The launch will follow the Falcon 9’s anticipated December launch, from
Vandenberg Air Force Base, California, of 10 Iridium Communications
satellites into low Earth orbit. The Iridium launch will mark SpaceX’s
return to flight following the Sept. 1 explosion of a Falcon 9 as it
was being fueled in advance of a static test fire. (11/24)
ViaSat and O3b Could Clash in Medium
Orbit (Source: Space News)
Two satellite companies that currently operate in different orbits
could clash in medium Earth orbit. ViaSat, which operates satellites in
geostationary orbit, filed an application with the FCC last week for a
system of 24 satellites in medium Earth orbit at an inclination of 87
degrees.
The satellites would be at the same altitude at the system currently
operated by O3b, whose satellites are in equatorial orbits. O3b filed
three applications with the FCC last week as well to add additional
satellites and frequencies to its equatorial system, and also to
develop a 16-satellite system at a similar altitude, but at an
inclination of 70 degrees. (11/23)
With Hillary Out of the Way,
Right-Wing and Fake News Writers Target Elon (Source: QZ)
Fake news galvanized US president-elect Donald Trump’s supporters, and
sullied his enemies. Now it may be Elon Musk’s turn. The CEO of Tesla
and SpaceX has his fair share of detractors, but a new era in a public
relations battle to discredit him appears to be taking shape. Bloomberg
reports that hard-right groups are lining up to back misleading
websites and fake journalists who attack Musk’s business empire.
Many of the attacks on Musk begin with something factual: His
businesses were built, legally, with the help of billions in government
contracts and incentives for renewable energy and space transport. But
they go on to accuse Musk of fraud and wasting taxpayer dollars; some
compare him to a convicted felon. At least three conservative sites
have run negative pieces about Musk—by a nonexistent writer named
“Shepard Stewart”—that include “Elon Musk Continues to Blow Up Taxpayer
Money With Falcon 9” and “Elon Musk: Faux Free Marketeer and National
Disgrace.” Two later retracted the stories. (11/23)
Time to Take Out the Space Trash

Scientists are warning there’s now so much space debris in low-Earth
orbit that action needs to be taken. Next year, a new mission plans to
boldly go where no refuse collection has gone before. Click here.

Do Solar Neutrinos Affect Nuclear
Decay on Earth? (Source: Physics World)
Further evidence that solar neutrinos affect radioactive decay rates on
Earth has been put forth by a trio of physicists in the US. While
previous research looked at annual fluctuations in decay rates, the new
study presents evidence of oscillations that occur with frequencies
around 11 and 12.5 cycles per year. The latter oscillation appears to
match patterns in neutrino-detection data from the Super-Kamiokande
observatory, in Japan. Other physicists, however, are not convinced by
the claim.
The idea of fluctuating beta-decay rates is very controversial because
for more than 80 years, radioactive substances have been thought to
follow a fixed exponential decay, under all conditions. In recent
years, however, there have been suggestions that decay rates are not
constant and are influenced by the Sun. In 2009, physicists from Purdue
University in Indiana published a paper discussing unexplained annual
fluctuations in long-term measurements of decay rates of silicon-32 and
chlorine-36. (11/24)
Britain Endorses ESA, Promises
Increased Export-Credit Support for Industry (Source: Space News)
The British government has emphatically endorsed its investment in the
22-nation European Space Agency and rejected a parliamentary proposal
that its space budget be more evenly divided between ESA and a national
program. Countering the centrifugal trend in Europe — highlighted by
the U.K. decision to quit the European Union — the government
reaffirmed that Brexit will have no effect on the UK role in ESA.

Spaceport America’s New Director Faces
a Tough Challenge (Source: Albuquerque Journal)
Meet Dan Hicks, Spaceport America’s newest executive director. A month
into the job, the longtime civilian executive at White Sands Missile
Range inherits an immense challenge: taking the $218.5 million
taxpayer-funded facility and turning it into the self-sustaining
success many of its supporters hoped it would be by now. It’s a task
that must be accomplished under the pressures of a shrinking state
budget, slower-than-expected progress by anchor tenant Virgin Galactic
and a hyper-competitive commercial space environment – the pool from
which Spaceport aims to draw customers. (11/25)
Trump or NASA – Who’s Really
Politicizing Climate Science? (Source: The Conversation)
Climate research conducted at NASA had been “heavily politicized”, said
Robert Walker, a senior adviser to US President-elect Donald Trump.
This has led him to recommend stripping funding for climate research at
NASA. Walker’s claim comes with a great deal of irony. Over the past
few decades, climate science has indeed become heavily politicized. But
it is ideological partisans cut from the same cloth as Walker who
engineered such a polarized situation.
Believe it or not, climate change used to be a bipartisan issue. In
1988, Republican George H.W. Bush pledged to “fight the greenhouse
effect with the White House effect”. Since those idealistic days when
conservatives and liberals marched hand-in-hand towards a safer climate
future, the level of public discourse has deteriorated. Surveys of the
US public over the past few decades show Democrats and Republicans
growing further apart in their attitudes and beliefs about climate
change.
For example, when asked whether most scientists agree on global
warming, perceived consensus among Democrats has steadily increased
over the last two decades. In contrast, perceived consensus among
Republicans has been in stasis at around 50%. How is it that party
affiliation has become such a strong driver of people’s views about
scientific topics? Click here.

Astronauts Enjoy a Zero-Gravity
'Spacegiving' Dinner (Source: Reuters)
An international crew of astronauts celebrated Thanksgiving on Thursday
with a special 'spacegiving feast' of rehydrated foods on board the
International Space Station. NASA published a photograph of the six
astronauts enjoying their meal, which included rehydrated turkey,
stuffing, potatoes and vegetables. The meal was rounded off with cherry
blueberry cobbler for dessert, NASA Commander Shane Kimbrough said in a
preview statement made some 200 miles (320 km) from earth on Nov 18.

Satellites Confirm Sinking of San
Francisco Tower (Source: ESA)
The Sentinel-1 satellites have shown that the Millennium Tower
skyscraper in the centre of San Francisco is sinking by a few
centimetres a year. Studying the city is helping scientists to improve
the monitoring of urban ground movements, particularly for subsidence
hotspots in Europe. Completed in 2009, the 58-storey Millennium Tower
has recently been showing signs of sinking and tilting. Although the
cause has not been pinpointed, it is believed that the movements are
connected to the supporting piles not firmly resting on bedrock.
